If you have ever had a black car and you were shocked by the temperature inside after leaving it for a while in the sun, you probably wondered if the color of the vehicle had an impact.

Is it true that black cars warm more quickly than those of other colors? The answer is yes. If you leave a white and a black car parked in the sun for the same period, you will discover that the interior of the white car is much fresher than that of the black car.
This curious phenomenon has been tested in one Study of 2011 conducted by researchers of the Environmental Energy Technologies Division of Berkeley Lab. They have discovered that light -colored cars reflect almost 60% of sunlight, while the dark ones absorb most of them.
For the tests, the researchers left two Honda Civic, one silver and the other black, under the sun on a warm day in Sacramento, in California (USA). After an hour, they discovered that the interior of the black car was hotter than 5 or 6 degrees Celsius than the silver.
In addition to the internal heat, the researchers have discovered that the clear paint also improves the efficiency of the vehicle, since it requires less use of the air conditioning to maintain a comfortable temperature. This involves a 2% fuel saving and a reduction in carbon emissions also close to 2%.
But why does all this happen? One of the reasons is that black surfaces absorb more sunlight and transform it into heat, making the passenger compartment perceived hottest.
In addition, black cars radiate heat more efficiently than light color, which means that the heat absorbed by the surface is more likely to be released black, cars, black paint, black cars warmer more?, Hot cars, study, myth or truth, research, reality or fictionalized in the surrounding air rather than reflection.
Although other factors, such as the corner of the sun or materials used in the construction of the car, can have an impact, in general the dark colors tend to absorb more heat than the light.
